About Project

The Home HVAC model was designed and built as an experimental test-bed for developing a smart HVAC control system. The model itself uses the design principle of independance of functional requirements to give as much flexability to the model as possibile; this allows for many interesting scenarios and experiements to be run in a controled system before implementing them in an actual home system. The purpose for the control system is to limit the temperature differential within a room and between rooms to make for a consistant and comfortable living enviroment. This is accomplished through the use of mechanical systems, electrical systems, and software. The idea for the project came from a personal dissatisfaction team members have with drafty rooms, hot and cold spots, and unresponsive thermostats in our own homes.

Team Info

Ned Cameron
Ned is a senior in the Mechanical Engineering department. He has concentrated in MEMS, Nanotechnology, and Mechatronics while fulfilling the requirements for his degree. After graduation, he will work as Application Service Engineer for Informance International in Northbrook, IL.
Ted Reynolds
Ted is a senior in the Mechanical Engineering department. He is a co-op engineer with ITW in Glenview where he plays on the volleyball team. He enjoys sleeping little and cooking lots. Considering he still has another year left, Ted has not given much thought to his future, but wherever he may be, he plans to have the best HVAC system on the block.
James Snyder
James is a first year graduate student in Biomedical Engineering. He has recently completed an undergraduate degree in biology at Northwestern University (concentration in Neurobiology), and currently works with the MacIver Lab studying sensorimotor integration in weakly-electric fish.
